Abstract
A wireless sensor capable of sensing and measuring at least one ambient parameter is disclosed herein. The wireless sensor is capable of transmission of measurement values at a periodic rate, wherein the transmission rate is varied or non-varied. An amplifier varies a power transmission to the antenna based on a real-time soil conductivity value of a soil area and a real-time soil dielectric constant value of a soil area to improve a communication range and communication reliability of the antenna.
